EMBROIDERY-HOOP.

Specification of Letters IPatent.

Application filed November 19, 1914. Serial No. 872,978.

To all whom it may concern:

Be it known that I, WALTER A. FINLEY, a citizen of the United States,residing at Fairmont, in the county of Marion and State "of WestVirginia, have invented certain new and useful Improvements inEmbroidery- Hoops, ofwhich the following is a specification. Thisinvention relates to an improvement in embroidery hoops, and one of theprincipal objects of the invention is to provide an 1 improved means forcompressing the outer ring of "the hoop upon the inner ring, whereby tosecure and maintain the cloth upon the hoo 1 compressing the outer splitring upon the inner one, includiiigmeans for adjusting the throw of thelever whereby the range of adjustment of the outer ring may be varied.

A further object of the invention is to provide a device of the classdescribed which will be extremely simple, durable, efficient inoperation and inexpensive to manufac- -With these and other objects inview which will become apparent as the description proceeds, theinvention resides in the construction, combination and arrangement ofparts, hereinafter more fully described and claimed, and illustrated inthe accomi of an embroidery hoop constructed according to my invention,the lever being shown in open position. Fig. 2 represents a view similarto Fig. 1, thelever being shown in locked or closed position.

Fig- 3 represents a view similar to Fig. 1,

showing a modified form of the outer hoop and operating mechanism.

Fig. 4 represents a view of the same showing the lever in closed orlocked position.

partially in section of the adjusting sleeve and trunnion towhich it isswiveled.

The form of hoop shown in Figs. 1 and 2 includes an IIIIIGP'COHUIIUOUSring 5 and aniouter split ring 6. One end 7 of the outer ring overhangsthe opposite end 8 thereof and lsofi -set from the body portion of theouter ring so as to be spaced a distance from the inner ring 5substantially equal to or slightly greater than the thickness of end 8of the other ring. This off-set end 7 may Patented Dec. 4, 191?.

thus overhang theend 8 in the manner indicated in Figs. 1 and 2.

A pair of ears 9 extend outwardly from the outer or free end of off-setsections 7,

and a pair of ears 10 eXten d outwardly from the free terminal of end'8of the outer ring,

the said ears 10 beingp'ositioned on both S1ClGS of off-set sections 7,so as to embrace and guide the same between them. Pivoted Another ob ectof the invention 18 to provide an improved lever operable means for atone end between ears 10, is a lever 11.

T he latter issubstantially of an inverted U-shape in cross section; Athreaded bolt or pin 12 is at one end pivotally connected to lever 11between its sides and adjacent the point 13 at which saidlever ispivoted to ears 10. Bolt 12 at its pivot end is provided with an eye 14through which a pin 15, carried by the walls of lever llextends.

The outer or opposite end of bolt 12 is threaded and has turnedthereupon a hollow knurled sleeve or swivel nut 16. SleevelG atits outerend is rotatably carried by a trunnion 17 which is pivoted byIIlQflllSOf its arms 18 between the ears9 carried by oif-setend 7 of theouter. hoop ring. The structure of the sleeve and trunnion is indicatedin Fig. 6. It will be noted that sleeve 16 carries a stud or pin 19which extends through trunnion 17 and has a head 20 counter sunk in thetrunnion. This structure allows of the sleeve being rotated relativelyto the trunnionwithout danger of its being lost therefrom;

Lever 11 is indicated in open position in Fig. 1, and by forcing saidlever downwardly into theposition shown inFig. 2 the outer ring willbetightened upon the inner ring of the hoop. so as tobind the cloth,which has previously been disposed between the rings, securely upon theinner ring. It will be noted that the lever 11 is of' a curvaturesubstantially equal to the curvature of the rings. and that by reason ofits being of a channel or inverted U shape. the bolt 12 The embodimentindicated in Figs. 3, 4 and 5, provides a continuous inner ring 5 and a.split outer ring 6 The ends of the latter do not overlap, but onthecontrary are spaced slightly-aparq'so that order to tighten thisouter ring 6 it will be necessary to draw the ends of the ring togetherrather than to press them apart as occurred in the operation'of theouter ring shown-in Figs. 1 and 2. I employ a lever operated mechanismto, obtain this result, substantially similarinprincipal of operation'tothe mechanism l have .described, the main difference being that thelever is operated in an'opposite directionl'rom that shown in Figsiiland. 2.

in Figs. 3.t 5 inclusive theleveris indicated at 11" and is pivoted atits inner end at 13 between a pair ofielongated ears provided on oneendof split ring" 6. One end of=a threaded bolt or pin l2 is pivoted atbetween .-the Walls of lever 11 in the manner similar-to the manner inWhichthe bolt 12 ispivoted to lever 11, and

the opposite end 013 a bolt 12 carries a r '-sleeve 16 'si1nilartossleeve 16 and like the latter is swiveledtoatrunnion17 pivotedbetweena pairof ears 9 carried by the opfipositeendofthe split ring- GThe structure of the last mentioned sleeve-and trunnion is exactlysimilar to that shown in Fig. 6. The bolt 12* adjacent lever 11 is bowedupwardly as at 2l, soas not to engage against the pin 13 on which lever11 is pivoted, whenfsaid'lever is in closed position as'indicated inFig.4. The-back oflever 11 is slotted or i'ecessedas at 22 to allow roomfor *.the adjacent portion of bolt 12 to play.

"Inithe modified form just described, the router ring isindicatediin'open" position as inlFig. 3 and in closed or compressedposiation in igwl, andit will benoted that in 40 iclosingtorflocking theringdever 11 is f'forced' downwardlyto the left or away from theopposite free end of the outer ring. This'movement of the leverwhilebeing oppositsto the'movelnent of the lever indicated *"in Figshlandfiobtains the'same result, in that it? draws the outer ring tightly uponthe inner ring. The lugs 10 are isubs'tantially equal to or slightly'rgr eater' in Y dimensions than the lever Il -iFSOLt'hat when "saidlever. is in closed 1 position it will "be :substantially "housedbetween the l-ugs IO.

Iniboth forms shown vin the drawing, the "-jthrow of'the =lever, and"consequently the range of adjustmentfof theroutenrin-g, may :be varied'by' the operation 'of the same ele- Jment; namely; the threaded" sleeveor swivel 'in'ut 16 sln the first "GIIIlJOfllIIIEIliZ'ZSllOWD theseisleeve'may be turned insu'ch A direction as to 'riincrease thedistance between i the pivot po'ints'13 and :18.in orderrtoi'obtain 'anincreased tightness of ther outerliring when the lever'2is inlocked-2pcsitionrasindicated in] Elgar. Q""Il1(linether'embodimentimdlcated in 1 wifF igs; ,A" andl'5 the'sleeveslftisamay heztnrned to decrease the distance between the pivot"points l3 and 18 in order to secure an increased. tightness of.t'heiouter ring when the lever is in locked position.

' lt-wi ll be noted that in both embodiments the point of connection ofthe lever and bolt is out ofalinement with a straightllineaednnectingthe pivot points of the lever and sleeve or trunnion, and is betweensaid straight line and. ithev.ho op, wvhengthe -lever is in closed Orlockedpostion, o that the tension of the outer hoop operatesto maintainthelever in tlRLt POSlti'ODp rather than to tend to raise the leve ifromitsglocked position. In this manner V the operation .is similar to thatofa togglefllever, and the lever once having been locked is notlikely tobecome accidentally :unlocked but must be V forced 'into openpo sitionin order to unbind 0r1l00S811 the outer ring upon theinner one. It willbe'noted in both embodlments, that i there are fno projecting or =1sharp pointsor obstructions which might tend to catch: the

thread during the process of embroider-mg cloth uponthe iihoop. In Iboth "instances quick. adjustment ofthe outer hoop may be had by simplyturning the sleeve or} nut 16 or 16 as the case may ibeinthedirectiondesired in orderithat various thicknesses of cloth maybeaccommodated. A7

combination and arrangement of-partsthereof as do not depart'from thespirit of'theinvention and thescopeof the appended claims. I V
